Meteor, scoping object instances to Events and Helpers

Now and again you might want to extract out complex logic into its own class and access instances of shared functionality via your Helpers and Events. Ideally what I want to do is create an instance in the created hook and then make use of that instance in the Helpers and Events. This is the solution I came up with - I’m not sure if it’s the correct approach but I haven’t seen anything better yet.
